Factors Affecting The Quality Of Fiber Laser Welding Machine Handheld

Traditional welding machine is bulky, slow construction efficiency, poor results, so now the emergence of fiber laser welding machine handheld slowly eliminate the traditional welding equipment, it is delicate and compact, built-in structure arrangement compact and more reasonable, one person can move, easy to operate, the effect is more excellent, the cost of welding is also lower, more in line with modern work needs, and compared to the traditional welding method is very small harm to human body.

The fiber laser welding machine handheld adopts the latest generation of fiber lasers and is equipped with a self-developed wobble welding head to fill the gap of handheld laser welding machine  in the laser equipment industry. It has the advantages of simple operation, beautiful weld seam, fast welding speed and no consumables. Welding of metal materials such as stainless steel plates, iron plates, and galvanized plates can perfectly replace traditional argon arc welding and electric welding. The hand-held laser welding machine can be widely used in complex and irregular welding processes in cabinet kitchens, stair elevators, shelves, ovens, stainless steel door and window guardrails, distribution boxes, stainless steel homes and other industries.

Several factors affecting the quality of handheld laser welding (For Reference):

1. Laser source (such as fiber laser core diameter 14um 50um 100um)

2. Lens selection (collimating lens and focusing lens accessories selection)

3. Focal length adjustment: positive focus and negative focus (commonly used 150mm, customized 125mm, 250mm 600mm, etc.)

4. Laser output power adjustment

5. The moving speed of the operator's hand and the speed of the wire feeding

6. Airflow: direct blowing and side blowing

7. The material itself: the surface has oil stains, galvanized, oxide layers, etc.

8. Auxiliary fixture

Fiber Laser Welding Machine Handheld Features :

Integrated structure design, comply with majority of the laser source available in the market;

Low running cost, only 1~2Kw/h electricity and little nozzle cost;

Dual-temperature control water chiller, support both laser source and welding head, ensure long term stable operation;

O-type, Line-type and dot-type wobble welding types for option, swing width ranges 0~5mm;

Equips digital display barometer, with low pressure alarm function to help adjusting air pressure;

Touch screen control panel, easy for parameter adjusting, less relying on skilled welding technicians;

Ergonomic design welding head, optional elastic weight reducer, make it easy for long time operation.

At present, the cooling system of fiber laser welding machine mainly includes water cooling, air cooling and water cooling. Among them, water cooling is widely used.

1. The chiller of the laser welding machine generally has a filter, which can effectively filter out the obvious particles in the water, keep the laser pump cavity clean, and prevent the possibility of water blocking.

2. The chiller uses pure water or deionized water, which is more conducive to the pump light source directly injecting the laser material, which can produce a better laser mode.

3. The chiller of the laser welder is generally equipped with a water pressure gauge, and you can know the water pressure in the laser waterway at a glance.

4. The chiller uses imported compressors, the water tank and pump are made of stainless steel, and the heat exchange coil is also made of stainless steel, so the stability of the chiller can be ensured, the cooling effect is very good, and the temperature accuracy control can reach 1 ℃ The temperature is small, and the laser is slightly affected by temperature, but we recommend setting the temperature to about 1 degree. . .

5. The chiller of the laser welding machine is generally 220V household power supply instead of 380V three-phase power supply, which is more conducive to the versatility of the equipment.

6. The chiller is equipped with flow protection. When the water flow is less than the set value, there will be a signal alarm, which can be used to protect the laser and related components from heat dissipation.

7. The chiller is equipped with temperature protection. If the temperature is not suitable, there will be a signal alarm.

8. There is also a water level alarm.

9. He chiller can realize a series of adjustment functions, such as temperature adjustment and temperature difference adjustment.

Handheld laser welding machine is mainly aimed at laser welding of long-distance and large workpieces. It overcomes the limitation of the worktable's stroke space. The heat-affected area during welding is small, and it will not cause work deformation, blackening, and traces on the back. The welding depth is large, firm and fully melted. It can not only realize thermal conduction welding, but also continuous deep penetration welding, spot welding, butt welding, stitch welding, sealing welding, seam welding, etc.
